A bug report on the autoconf list recently reported that autoconf has been
producing configure files for several years now with a dependence on
tr[1], even though tr is not listed in the set of safe programs[2]. Since
there have been no bug reports about an inability to configure packages
because of the use of tr, I propose adding it to the set of approved
programs (note that autoconf already lists some portability issues to be
aware of when using tr[3]).
